Straightforward activation of metal-organic framework UiO-66 for oxidative desulfurization processes

A current overview of the oxidative desulfurization of fuels utilizing heat and solar light: from materials design to catalysis for clean energy

“…In a recent study, activation of UiO-66 was performed by incorporating anions into the framework via simple mixing with the respective salts, including TiCl 4 , ZrCl 4 and TiBr 4 . 187 Unfortunately, the introduction of Br anions engendered the deactivation of UiO-66, leading to a poorer desulfurization efficiency than pristine UiO-66 in the ODS system with H 2 O 2 at 50 1C (Fig. 16a).…”

Advances in Oxidative Desulfurization of Fuel Oils over MOFs-Based Heterogeneous Catalysts

“…In general, the defects in crystal materials are closely related to their properties. Thus, it is of great importance to prepare the defective crystal materials [32][33][34][35][36][37][38][39][40]. As for UiO-66(Zr), some methods have been developed to fabricate defective UiO-66(Zr).…”

Optimization study on deep extractive oxidative desulfurization with tetrabutylammonium bromide/polyethylene glycol DES

“…The results showed that the desulfurization system had excellent desulfurization efficiency of 97% for real oil under mild conditions. For EDS, traditional desulfurization solvents included N,N-dimethylformamide, acetonitrile and dimethyl sulfoxide, [16][17][18] whose volatility is harmful to humans and the environment. Ionic liquids (ILs) address the shortcomings of traditional solvents due to their low volatility, high thermal stability, chemical stability, non-ammability and exible designability.…”
